I'm interested in the process of automatically generating advice when a player is consistently struggling through parts of a game. Suppose I already know what advice I want to generate (e.g., "Press A twice to double-jump across long gaps"). My question is twofold:
- Has it been shown that this intervention can be useful to gamer experience?
- Has it been shown that excessive intervention will be ignored or will cause frustration?
References to game design or psychology research papers is a plus!
